The walls ofvthe body portion near the bottom converge to form acollecting chiamber or combiningtube l() which decreases in crosssectional area from itsinlet ll to its outlet l2. A'castiig 13,(by meansof bolts let, is secured to the bodyportion and has a diffuser l5 formedtherein. The Walls 16 of the diffuser diverge so that its outlet 17 islarger than its inlet 18, which inlet is arranged axially Ain line withthe collecting chamber 10. Casting 13 is of such shape that a chamber 19is rovided whichV sur rounds and connects with the outlet of thecollecting chamber and the inlet of the diffuser. y Chamber l? isconnected to the condensing chamber by `sans of a passage 20 cored inthe bodl 'l j ion. andf'vhich terminates at one end "in a por, 2lleading into themendensinf"chamber and at the other end in a recess@which forms a portion of chamber 19. The passage 20 operates as anequalizing passitge and insures the same pressure in the chamber .19 asthat existing in the chamber 9. Avv 1th this arrangement' the stream ofliquid ejected from the outlet'12 does not have to overcome an. increaseof pressure in entering thechamber 19.

' A cover cast, in two sections 23 and 24 bolted together atQ is securedto the body portion by means of bolts 26.

Section 24 ot' the co'ver is cored so 'as to providey a water chamber 32having an inlet -l adaptedto be connected. to a suitable source ot'supply of condensing' water. The chamber 32 has a tubular all 34 whichsnrrounds thc hnbof the impeller and also has im outlet 3.7 providedwith partition. vanos 3l?. "lhc chamber 212 and th@l outlet 2. whichlaltcr may lic tei-mcd o now/.lc lic within the ring described bytheblalcs l The shaft is adapted to be rotatedat thev The faces 37 of theshroudsor ends of.

the .bladesdiverge; therefore, the Water projected by the blades 4willbe in. the nature of.. lil1ns or leaves of fan-like formation and at thevelocity imparted .to them will be projected toward the collectingchamber. In this Way a minute subdivision of thewater is attained `andit has been found that the' capacity of such a stream or jet forcondensing stcam'or vapor andfor removing air or other non-condensablefrases and uncondensed vapor, is extremely liigh.-

rThe operationof the device s as 'follows'.

rThe vstream comprising the succession of separate leaves or filmsofliquid discharged from the rotating impeller` travels downwardly throughthe chamber 9 and is received by the collecting chamber 10, Where it. iscompressed and' rendered more' compact and from which it is dischar ed,due to its initial velocity, into the d1 user or transformer Thevelocity ci the liquid is converted into pressure as theliquid.

traverses the diffuser. The films or leaves or' water discharged fromthe impeller blades operate as a series of separate pistons' l invtraversing the chamber 9 and the tube l() and thev .irremoved from thechamber 9 is conti ed between adjacent films or leaves and fis ejectedfrom the condensing chamber the Water.

I have found by experience that itias` de- I,

` srable to; have the separate leaves, orthe .stream composedof theseparate leaves, projected from'the impeller into the con- (lensing`chamber, at a point between the admission port, through which air entersthe chamber, and the discharge )ort from which the air is ejected.` In adition to this. I find it desirable tlconfine the leaves or -`1lms ofliquid by 'means of the walls of the tube ortubular passais throughwhich they more -in order to o tain the highest efficiency. By providingsuch a tube or passage, thc analogy between the operation olfv cachleaf, traversing the passage, and a,y piston will bc more marked.' Mytheory is, that the leal', at the time 'ot' its formation andlsubset]uently', must bc subjected to substantially equal pressures onboth sides, or else it will break into a muss of separato drops :md berenderedv loss cficctivc as a lluifl translating agent.A
